Hardeep Singh reported a problem doing HTTP POST with Digest. (It was actually

also affecting NTLM and Negotiate.) It turned out that if the server responded
with 100 Continue before the initial 401 response, libcurl didn't take care of
the response properly. Test case 245 and 246 added to verify this.
